HYDROCARBO N-BURNER.

SEEGIFIOATION formingpart of Letters Patent No. 679,015, dated July 23, 1901.

Application filed June 20, 1900.

T0 ctZZ whom, it may concern:

Be it known that I, JAcoB J. BUSENBENZ, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Hydrocarbon-Burners, of which the following is a specification.

My object is to provide certain improvements in the construction of hydrocarbonburners generally, though more especially of hydrocarbon-burners for incandescent vaporlamps, whereby a particularly strong and steady flame is produced and ready access to all parts of the interior of the burner may be had.

My object is, further, to provide such a burner in which the objectionable needlevalve and packing usually provided is dispensed with, and a vaporizing-tube beneath the burner is brought into particularly close proximity to the flame which heats it.

My object is, still further, to provide a simple and durable construction comparatively inexpensive to manufacture and particularly well'adapted for the purpose for which it is intended.

The drawing shows in broken section an incandescent vapor-lamp provided iwith a burner of my improved construction.

A is the base of the burner, comprising a metal block having the central upward-extending boss a, trough b, surrounding the boss, and opening 0 through the base, threaded in that part which extends through the boss a.

B is a vaporizing tube or chamber screwed upon a boss don the side of the base to communicate with a passage 01, leading to the opening 0. In the other side of the base, in line with the passage 61, is a threaded opening efor a valve 0. Fastened in the passage d and extending across the opening 0 is an inlet-tube f, provided in its upper side, centrally of the opening a, with an outlet or feedperforation f. The end of the tube f is fitted with a removable screw-plug f The valve 0 is provided in its end with a deep recess or sleeve portion g, at which it is adapted to fit and as it is screwed in and out to slide over the tube f to cover and uncover the opening f. \Vhen the valve 0 is closed, it seats at its inner end against a shoulder or valveseat (1 ain n. 20,978. on model.)

D is a burner-head, comprising an inner tube h, screwed at its lower end into the boss a, a ring 1', surrounding the lower end portion of the tube h, an outer tube 70, fitting at its lower end around the ringiagainst an annular horizontally-extending shoulder t, and a fine-mesh screen or burner-cap Z, removably fitted into the top of the tube It. The tube h, ring t', and tube is are fastened together in a suitable way, as by means of the pin on. The tube h terminates a short-distance below the top of the tube It, and the tubes together form an inner chamber or passage h, surrounded by an outer annular chamber 7t. Extending through the ring 7 are one or more openings 7?. Suspended from the block or base A is an alcohol-cup n, provided with the usual asbestos lining n. In the drawing I have shown a gallery 19, supported from the shoulder 12 of the ring 1', carrying a chimney 10, holding a shade p and mounted in the usual way is an incandescent mantle q. The vaporizing-tube B is filled with highly-refractory granular material r, and I prefer to employ No. 12 corundum. The tube B is fastened at its outer end to a pipe leading from a hydrocarbon-reservoir. The gasolene or other hydrocarbon enters the tube B and passes through the granular filler to the passage 01. When the valve Cis screwed inward, it effectively closes the outlet f and prevents escape of the gasolene.

In operation a little alcohol is poured into the cup n and ignited to heat the base A. The valve 0 is then screwed outward to open the feed-perforation f and permit gasolene vap orized by the heat of the base to escape. The gasolene-vapor will mix with air in the opening 0, rise in the tube It, and, filling the latter to the top, will sink downward in the chamber is, whereby it will escape through the burner-cap land through the openings 1 at both of which points it is ignited. The flame from the burner-cap plays against the mantle q to produce the desired incandescent light, and the flames from the openings i play against the base or block A to heat the same and to heat by conduction the vaporizing-tube B.

The construction involving the inner and outer tubes h k is very effective in producing a steady strong flame at the burner-cap Z, while the effect of the flames from the openings i playing against the base A, is to heat the same and the vaporizing-tube B to a very high temperature with attendant desirable results. The valve 0 is easily turned, by means of a handle (3', to thoroughly shut ofi the escape of gasolene when desired and possesses none of the objectionable features of the needle-valve usually employed in burners of this class. No packing is required, and this is a material advantage. When it is desired to clean the burner, the valve 0 may be screwed entirely out of the base A, and the screw-plug f may be removed from the tube f. This gives ready access to the latter.

What I claim as new, and desire to secure by Letters Patent, is

1. In a hydrocarbon-burner, the combination with a base, of a feed-tube therein having at one end a removable plug and between its ends a feed-perforation, a valve-seat surrounding the feed-tube, a valve having a sleeve portion surrounding the plug end portion'of said feed-tube and movable longitudinally thereon to and from said seat to open and close the feedperforation, a vertical burner-head comprising an inner tube secured to the base over the feed-perforation, and an outer tube carrying a burner-cap, and an apertnred gallery-supporting ring securing the burner-head tubes together at their lower end.

2. In a hydrocarbon-burner, the combination with a base, of a feed-tube therein provided at one end with a removable plug and between its ends with a feed-inlet perforation and surrounded by a valve-seat, an opening through the base in line with said feedtube, and a valve in said opening having a sleeve portion surrounding the plugged end portion of said feed-tube and movable longitudinally thereon to and from said seat to open and close said feed-inlet.
